HiMaybe it could help with some issues since MySQL was upgraded from 5.0 to 5.1. I know it is quite complicated to update Xampp by myself with a component like MySQL (it was very easy to update phpMyAdmin to 3.1.2). Maybe in the next Xampp 1.7.0 pl1 beta 6?

XAMPP full version releases always contain the current available versions of it's included components at time of compile, but not always in patch releases and it really only takes a read of the ApacheFriends Home Page to find this out.
